Create a new Token

In this chapter, we will focus on how to create a custom token on the Starcoin blockchain. Let's get started.


First, start a dev network described in How to set up a local dev network and get some coins, say 1000000000.

In this document, I will use 0xb19b07b76f00a8df445368a91c0547cc, the default account address of my dev network, to represent the person who issues and send the new token. And I also created another account 0x831d51f0087596e6aa4e7b3b9c85f945 and transfer some STC to it. The account will be used to receive the token.

The source file can be found at my-token.

Compile the module

Change the address of the module:

  • edit Move.toml
  • change MyToken = "0xABCDE" to MyToken = "0xb19b07b76f00a8df445368a91c0547cc"

Then open a console and run the following command:

$ mpm release

Packaging Modules:
Release done: release/my_token.v0.0.1.blob, package hash: 0xc3b9cf32499f4bdf0a38d57f7c7c66a6f4df69881a8980bcda2106782dce88ba

It will compile the module, and then you will get the binary package my_token.v0.0.1.blob in release folder. We will use it then.

Import account

We will need to import 0xb19b07b76f00a8df445368a91c0547cc account to deploy the module.

starcoin% account import -i 0x05c9d09cd06a49e99efd0308c64bfdfb57409e10bc9e2a57cb4330cd946b4e83 -p <MY-PASSWORD>

"ok": {
"address": "0xb19b07b76f00a8df445368a91c0547cc",
"is_default": false,
"is_readonly": false,
"public_key": "0x7932502fa3f8c9bc9c9bb994f718b9bd90e58a6cdb145e24769560d3c96254d2",
"receipt_identifier": "stc1pkxds0dm0qz5d73zndz53cp28esyfj4ue"

Get devnet test coins

Get some STC coin from dev net, and it will send 1000000000 STC to the account by default. Notice that, this command can only be used in dev net.

starcoin% dev get-coin 0xb19b07b76f00a8df445368a91c0547cc

Deploy module

Then, unlock the account and deploy MyToken module.

starcoin% account unlock 0xb19b07b76f00a8df445368a91c0547cc -p <MY-PASSWORD>
starcoin% dev deploy /path/to/my-token/release/my_token.v0.0.1.blob -s 0xb19b07b76f00a8df445368a91c0547cc -b

txn 0x686964d6a4212f1e32e8626132e14dabffb034d6f3aec921e80a2e54726391b1 submitted.

"raw": "0xc7610000000000000000000000000000"

You can see that the transation is submitted and the result status is Executed. That means the module has been deployed.

Execute script function

First,use the account 0xb19b07b76f00a8df445368a91c0547cc to initial module via init function.

starcoin% account execute-function --function 0xb19b07b76f00a8df445368a91c0547cc::MyToken::init -s 0xb19b07b76f00a8df445368a91c0547cc --blocking

Second, use the account 0xb19b07b76f00a8df445368a91c0547cc to mint some MyToken.

starcoin% account execute-function --function 0xb19b07b76f00a8df445368a91c0547cc::MyToken::mint --blocking --arg 1000000u128 -s 0xb19b07b76f00a8df445368a91c0547cc

Third, use the account 0xb19b07b76f00a8df445368a91c0547cc to transfer 1000 MyToken to another user 0x831d51f0087596e6aa4e7b3b9c85f945.

starcoin%  account execute-function --function 0x1::TransferScripts::peer_to_peer_v2 -t 0xb19b07b76f00a8df445368a91c0547cc::MyToken::MyToken --arg 0x831d51f0087596e6aa4e7b3b9c85f945 --arg 10000u128 -s 0xb19b07b76f00a8df445368a91c0547cc

Last, show balances of the second user.

starcoin% account show 0x831d51f0087596e6aa4e7b3b9c85f945
